Ligand Definition. A ligand is an atom, ion, or molecule that donates or shares one or more of its electrons through a covalent bond with a central atom or ion. It is a complexing group in coordination chemistry that stabilizes the central atom and determines it reactivity.
All four-Cl ligands get arranged in tetrahedral manner around the central metal ion and form a metal complex. Ligand can be an anion, cation or a neutral molecule. Neutral ligands must have a lone pair of electrons which can be donated to the metal atom or ion to form complexes. ligand can be defined as a specific substance that is capable of binding and forming a thermodynamically stable complex with other bio molecules through either ionic and hydrogen bonding or Van der Waals forces to perform a specific biologically important function.
